Explain how animals in Vertebrata are classified into further subgroups. Pisces and Tetrapoda. Animals of Pisces have streamlined body with fins and tails to assist in swimming.
Animals of Tetrapoda have four limbs for locomotion. Tetrapoda is further classified into following classes: a Amphibia: Are adapted to live in water and on land. Can breathe oxygen through skin when under water. Skin is hard to withstand extreme temperatures. Beaks are present. Body is covered with feathers. Skin is covered with hair.
